> Another way to do this in Gadfly: p = plot(z=(x,y)-\>Mandelbrot(x+y\*im), xmin=[-2.5], xmax=[1.0], ymin=[-1.75], ymax=[1.75], Stat.contour(levels=[10:30;], samples=200), Geom.path, Theme(panel\_fill="midnightblue") ) [Mandelbrot] Gadfly.spy is aimed at the quick plotting of numerical matrices e.g. where would expect to see the diagonal here?: using LinearAlgebra eye = Matrix(I,10,10) Gadfly.spy(eye)
